Timing Valve Operation

The Timing Valve is an extremely reliable and convenient means to automatically open or close the oil
passage. The built-in roller is activated by the Timing Valve Cam, causing a resultant movement of the
Timing Valve stem to open or close the oil passage. The Timing Valve is closed when the roller is fully
extended and it is open when the roller is depressed as illustrated in Figure 6.
